OK, I have a points system where I can have up to 1.3billion points. I need to find a way to convert the points into percentages. I found a way to come up with the points, but I have not been able to reverse it.

Now, how I got these point values was to take the point value for the number above and multiply by 1.18. (So, 102 = 100 * 1.18 = 118, 103 = 118 * 1.18 = 139.24, 200 = 1,107,737,137.71 * 1.18 = 1,307,129,822.50)

What I'm looking for is one equation that will work to convert all of these point amounts to their respective percentage amount.

Is there one such equation that will work and what is it? I beg you for you genius as I just can't wrap my mind around how to get this equation right.

Thank you. This is exactly what I need and through testing, it does work as I wanted. I'm glad I was able to explain it clearly enough and even more importantly, I'm glad you were able to come up with the answer so quickly for me.
